As shown in the drawings, I have selected "UNITED STATES reruns.WILLIAMO. KLEINE,= OF CINCINNATI, OHIO.

in its respective radial slots 16. Secured by Application filed January24, 1922'. Serial No. 531,484.

for illustration a particular construction. des gned for boulevardstreet lighting posts,

and for mounting the holder I provide an annular plate or sub-base 1,open in the center and with a bridge piece 2, which, in the ,60

ed to oscillate thereon is. the annular base plate 6 with a peripheralupturned flange 7.-

The outer portion ofthe'base plate 6 is depressed at'8 and the sub-baseplated iseofitset at 9 so as to allow an annular space 10 for clearanceof bolt heads and other devices mounted onthe base. I

The base plate6 is provided with aplu- ,rality of arcuate slots 12 forthe reception of studs, supporting cam pieces and clamp plates employed,and, as illustrated, I have provided for three of such studs, cam piecesand clamp plates, set 120 degreesapart,

, whichI found sufficient, although the number may be more or less.Mounted in these slots arethe projecting studs 13 secured to thesub-base platel, through the openings l5 by nuts or in any othersuitable way. The studs13 each carry a U-shaped piece 15 mounted tooscillate around the stud which passes through openings in the open endof the U-shaped piece. Thebase 6 is, also provided with short radialslots 16 corresponding in number to the slots 12 and the, U-shapedpieces each have a dog 17 or downwardly projecting are which engagesrivets or otherwise to the fiat upper portion of each U ohaped piece isa resillent plate 18 curved slightly upwardly at it'sfree end, and theseplates serve as the clamp plates for the globe and turn freely aroundthe studs 13.

The eifect of this turning will change the 11 position of the studs 13from one end to the other of the slots 12 and the retention of theU-shaped pieces 15 by the dogs 17 will cause the U-shaped pieces and theclamp plates to turn from the position shown in Figure 8 to that shownin Figure 2 or vice versa, the U-shaped pieces acting as cams, and thelengths of the slots 12 are such as to limit the travel and to preventthe clamp plates from coming in contact with the lamp socket when turnedin and to extend the clamps out radially when turned in the otherdirection.

Riveted or otherwise secured to the base 6 and preferably intermediatethe clamp plate mountings are flat plates 20 of resilient material whichserve as seats for the globe. These plates and also the clamp plates arepreferably constructed of phosphor bronze, because of its heat resistingand rust-proof qualities, and the flat plates have freedom of movementin the depressed portion 8 of the base.

With the clamp plates 18 turned as shown in Figure 8, the globe 21 isseated on the resilient plates 20 within the flange of the base and thebase is then turned to throw the. clamps outwardly, which brings theouter edges of the clamps to bear on the inside of the ridge of theglobe, holding the globe down on the resilient seat plates 20.

In order to lock. the base plate 6, the ears 19, which are riveted tothe flanges of the base plate 6 by an angle plate 28, are formed with adepending portion 22 which engages in the slots 24: in an extension 25from the sub-base 1.

In order to adjust and to regulate the tension of the clamp plates 18,each plate is provided with a set screw having an upset head 26 andscrewed into the cam piece 15.

The operation of the holder is exceedingly simple. To secure it in placeon the standard or post, the base plate 6 is provided with holes 27which are in such position so as to make accessible the attachingscrews, which are passed through the holes 5 in the subbase. The base isturned so as to unlock the clamps, and the globe is inserted in positionand the base plate turned, forcing the clamps to slide over and on topof the inside ridge of the globe securely holding it in position.

The clamps and the seat plates being of resilient metal, the globe ispractically held in suspension between the two springs and this alsoautomatically takes care of expansion and contraction. The clamp andseat plates act as a cushion both vertically and laterally.

The glass globe will therefore be protected against breakage due to anysudden jar or impact, as well as breakage due to general vibration,which in the case of ordinary holders, where the glass globe restsdirectly on the cast iron base, causes a chipping of the globe at thebase, or total breakage due to the glass coming into contact with theiron sides.

There being a complete absence of screws to hold the globe in place, itis impossible to break the globe by forcing screws in too far againstthe glass and not allowing "for expansion and contraction, as is thecase with ordinary holders.

It is also a great time and labor saving device, obviating as it doesthe necessity for securing the globe with screws; the simple movement ofthe base plate a distance of: slightly more than one inchinstantaneously either locking in position or opening the holder.

The peripheral depression in the base plate, in addition to providingspace for the resilient movement of the seat plates, also serves as awater shed or gutter preventing water from running down inside of thestandard or post and openings 29 are pro vided to discharge any watercollecting in the gutter.

Having thus described my invention, what I claim as new and which Idesire to secure by Letters Patent, is:-

1. In a device of the character described, the combination with a fixedsupporting plate and a base plate mounted to rotate thereon, ofrotatable clamp plates, cam pieces upon which the clamp plates aremounted and secured to one plate and in engagement with the other,whereby the movement of the base plate will cause the clamp plates toengage the globe resiliently, securely holding the latter in position,and resilient members secured to the base plate upon which the globe mayrest.

2. In a device of the character described, the combination with a fixedsupporting plate and a base plate mounted to rotate thereon, studsmounted on the fixed supporting plate and projecting through slots inthe base plate, a cam member mounted on each stud, with connection forthe cam member with the base plate, and a resilient clamp plate carriedby the cam member, whereby the rotation of the base plate causes the cammember to rotate and to throw the clamp member in and out of operation.

3. In a device of the character described, the combination with a fixedsupporting plate and a base plate mounted to rotate thereon, studsmounted on the fixed supporting plate and projecting through slots inthe base plate, a cam member mounted on each stud, with connection forthe cam member with the base plate, and a resilient clam 7 plate carriedby the cam member, with means for adjusting the tension of the clampplate, whereby the rotation of the base plate causes the cam member torotate and to throw the clamp member in and out of operation.

4. In a device of the character described, the combination with a fixedsupporting plate and a base plate mounted to rotate thereon, withresilient members secured to the base plate upon which the globe mayrest, studs mounted on the fixed supporting plate and projecting throughslots in the base plate, a cam member mounted on each stud, withconnection for the cam member with the base plate, and a resilient clampplate carried by the cam member,whereby the rotation of the base platecauses the cam member to rotate and to throw the clamp member in and outof operation.

& 5. In a device of the character described, a relatively fixed plate,with resilient supports thereon for a light shade, a plate mounted tooscillate on the relatively fixed plate, shade holders to engage theshade from the inside, and mechanism intermediate the two plates wherebythe movement of the oscillating plate will oscillate the shade holdersto engage the shade from the inside.
